Question

NaoH में उपस्थित प्रत्येक तत्व का द्रव्यमान प्रतिशत ज्ञात कीजिए​

Answer 1

Given:-

The Chemical compound NaOH

To Find:-

The mass Percentage of each elements

Solution:-

Mass percentage of element =  mass of the element/Total mass of the compound *100

• Mass of the Na= 23u
• Mass of the O (Oxygen)= 16u
• Mass of the H (Hydrogen)= 1u
• And Total mass of the Compound NaOH = 23+16+1= 40u
• So The mass Percentage of each elements are as follows:-

1. Mass Percentage of Na= 23/40 *100 = 57.5%
2. Mass Percentage of O= 16/40 *100 = 40%
3. Mass Percentage of H = 1/40 *100 = 2.5%
